That's the correct way. We knuckle busters installed circuit
breakers
in cars with hi-power stereos because transient currents could and
would break normal fusing. That was before they were running enough
amperage and speakerage to blow the hatches half an inch off their
seals. I can't imagine the overpressure in the vehicle, matched
with
the decibels of the Rap (which I still refuse to call "music") does
their brains or bodies any good.

I read an automotive paper about vehicle suspension frequencies to
avoid because they could unpleasantly resonate internal organs. I
couldn't generate them at a high enough power level to notice
anything, although my stereo can rattle the doors and windows.

The heavy and flexible cable for car audio has been useful in my
alternate energy projects.
